1/ '0 all whom it may concern:

Be it known tlat I, Tnonnui J. C00, 3. suhject of the King of Great Britain, residing in the city of Toronto, Province of On tario. Dominion of lauada, have invented certain new and useful Improvements in 'l' vpc-llriting Machines. of which the following is a specification.

This invention relates to typewriting niachines having divided platens, and has espe cial reference to the means for rotating the platen sections.

In typewriting machines of the divided platen type, one section of the platen is usually used for holding a bill sheet and the a ledger leaf. \Vhen the hill is written. certain data are transferred to the ledger leaf and then the platen section carrying the bill sheet is actuated to eject the bill and introduce another bill in its place. 1

In the present invention means are preferably provided. adjacent to the actuating means for the platen section carryii'ig the hill sheet. for quickly actuating the second platen scrt on to quickly introduce, feed, or eject thr ledger sheet. Those two actuating mcaus are arranged compactly and disposed so that they can be readily operated separately or suuultanrously with one hand or linger of tile operator. Thus the bill sheet and ledger sheet can he introduced simultaucously into the machine and together quickly mow-d for the major portion of the uci-cssary to adjust the sheets to the proper position For writing. The hill may then he \iriltcn. the data transl'rrrcd to the lrilgcr shoot. and llicn both can be ejected siioullancousl v. it several bills are to he written to the anir party. one of the quick actuating devices may be operated for introducing and circling the hills, and when the last bill has la-c-n written. both of the quick actuating ilciircs may be operated si1nulto eje t both the bill and the This results in a considerable ledger lcal time. as two dlstmct operations saving ol' can he pirl'oriucd separately or sinlultanov ouslr w th little eli'ort or thought on the par? of the operator.

in the w-ei'orrcd form of the invention, on the still l(,'\('." which carries the pawl engag ing the re tchct ol' the platen section used for the hil sh rts. l mount ill additional pawl on the othe side thereof to engage a ratchet wheel connected to the ledger platen section. The stub lever is thus mounted between two ratchet wheels, either one of which or both may be enga ed by the pawls on the stub lever. One 0 the pawls has a handle which projects outwardly longitudinally thereof, and the other pawl is shorter than the first pawl and has a handle projecting laterally thereof. Either one of these handles may thus be easily picked out and grasped by the operator to actuate the deslred platen section. whereas, if it is desired to actuate both. platen sections simultaneously. both handles may be readily grasped and operatcd together.

Other features and advantages will hereinafter appear.

In the accompanying drawings, Figure l is a plan view partly in section of a divided platen with my improved actuating means mounted on the platen axle. Fig. 2 is a perspective view of the improved constructions. one of the platen sections being detached for the sake of clearness. Figs. 3, 4 and 5 illustrate sections taken respectively along lines 3-3, 4% and 5--5 of Fig. 1 looking in the direction of the arrows.

The platen axle l'has at its ends usual platen turning knobs 2 and the paper feed ratchet 3 connected thereto. The platen comprises two separately rotatable sections 4 and 5. The platen section 4 is fast on a tubular shaft 4" extending the length of the axle between its hearings in the carriage, while the platen section 5 is loose and has fast thereto at its outer end the finger wheel ll. whereby it may be rotated by hand. lliountcd on the axle, at the end opposite to that carrying the paper feed ratchet are means which may quickly rotate the first platen section 4 to introduce or eject a bill or some such paper on which little writing is done in proportion to its size. These means consist of a lever 7 carrying a. pawl 8 engaging a ratchet wheel 9 connected to the platen axle. This lever is mounted on a stub lever 10 which is loose upon the axle and the pawl 8 is normall kept out of en'- gaflcmcnt with the ratchet by a spring 11 lived to the stub lever and hearing against the lever 7 to hold the same against a lug 12 formed on the stub lever.

The loose platen section may be used for holding a ledger leaf or some such paper upon which data. is transferred, and in order that this platen section may also be quickly rotated inde u-ndcntly of the first section or simultaneously therewith, l mount on the opposite side of the stub lever another lever 13 carrying a pawl ii to, engage a ratchet wheel 15 fast on the loose platen section. This lever i l extends farther forward than lever T and has preferably an elongated finer piece 16 which can be readily grasped and distinguished by touch from the handle 17 of lever T. The latter handle extends laterally and can also be readily grasped and distinguished from the handle on the other lev r Vv'hen it is desired to actuate both platens simultaneously, both levers 7 and 13 may be grasped together and both ratchet wheels 9 and 15 may be rotifiat one and the same time to actuate their respective platen sections.

A spring 18 may be provided also for is ver 13 to hold it normally against lug 19 on the stub lever out of engagement with the ratchet wheel 15. The ratchet wheels are provided with shoulders 20 and 21 which abut the stub lever and hold the same clear of the ratchet teeth.

A detcnt 22 may also be supplied for the ratchet wheel 15 to hold the corresponding platen section in proper line spacing position. The other platen section may be tovided with the usual detent (not shown to engage the paper feed ratchet 3, and said ratchet wheel may be engaged by the usual line space pawl 23 which is operated by the ordinary carriage return handle, not shown. The platen and its appurtenances arc journaled in the usual bearings 24:, 25 adjacent. the and heels 2, and the sleeve l carrying the section 4 of the platen extends substantially from one bearing to the other.

A shoulder 26 on said platen section 4 is arranged to form a ]ournal for the platen section 5. Said section 5 preferably is formed with a metal collar 27 having a flange 28, which collar bears against the shoulder and face of said section 4, an obtains a wide bearing thereon.

The opposite end of said section 5 adjacent the line space wheel 15 carries a collar 28, which bears on the sleeve 4. Thus it will be seen that the sleeve t, which is of considerable diameter and has great stillness, will properly support the center Where the two sections of the platen may join, and will carry the load of said platens out to the end of the axle adjacent the bearings 24 and 25. In this way, liability of spreading occurring at the joint where the section 4 meets section is avoi e The construction above described is very simple, com pact and ellicient. The arrange moot of both ratchet actuating levers on the same stub lever reduces the number of parts, and sa es in material and Space. of the arrangement and proportioning of By reason levers and handles the actuating means for each platen section may be easily picked out with a minimum of mental effort, and when it is desired to actuate both platens simultaneously it may be accomplished with the use of one hand operating with similar ease both of the above actuating means together.

Variations may be resorted to within the scope of the invention, and portions of the improvements may be used Without others.
